Renowned collector and Wall Street money manager William H. Gross sold pieces from his unparalleled U.S. stamp collection for the first time at an auction at the Robert A. Siegel Auction Galleries here in New York on April 9. Since 2008, Bill and his wife Sue have donated over $19 million to the Millennium Villages project, and they continued their generosity by donating the proceeds from the auction to the Earth Institute and to Doctors Without Borders.
